based on your information,

you can do like @Mahfuz Shishir answer

or

create new appends attribute inside Object Model

protected $appends = ['data'];

public function getDataAttribute()
{
     if($this->attributes['type'] == 1) {
         return Inst::where('inst_column', $this->attributes['object_column_to_match']); //this just sample
     } else {
         return Report::where('inst_column', $this->attributes['object_column_to_match']); //this just sample
     }
}

The relation looks like.

In your Object.php Model

public function containers()
{
    return $this->hasMany('App\Container', 'foreign_id');
}

And in your Container.php Model

public function object()
{
    return $this->belongsTo('App\Object', 'foreign_id');
}

You provide little information. Implement rest of the controller code in your own sense. Or put some code that you have tried.
